Metal Spur Ring Gear

The metal spur ring gear is a fixed component of the planetary gear system in a food processor, engaging with the planetary gears to transmit power. Our powder metallurgy metal spur ring gear use iron material, ensuring strength while also providing excellent vibration damping and noise reduction characteristics. The integral molding process avoids the cumulative errors associated with traditional welding or assembly, ensuring the stability and reliability of the transmission system.

Product Feature And Application

Powder metallurgy pressing is a high-efficiency, near-net-shape manufacturing process for metal parts, ideal for mass-producing high-precision, structurally complex components. Its core advantages include:
（1）Material utilization exceeds 95%, with almost no machining waste, aligning with sustainable manufacturing principles.
（2）Suitable for mass production, ensuring stable part dimensions, uniform mechanical properties, and strong quality control.
High Precision & Good Surface Quality
（3）Achieves high dimensional accuracy in a single pressing (typically IT7-IT9 tolerance), with excellent surface finish, reducing the need for secondary machining.
Ability to Form Complex Geometries
（4）Capable of producing parts with steps, curved surfaces, tooth profiles, and irregular holes ( gears, gear rings) through precision mold design.
（5）Allows optimization of hardness, wear resistance, and strength by adjusting powder composition, ratios, and post-treatments (e.g., carburizing, sinter hardening).
Application Examples in Household Mixer Accessories
The transmission system in household mixers requires low noise, high wear resistance, smooth operation, and controlled costs. Powder compaction molding provides an ideal solution for such precision gear components
